Pattern designing method, pattern designing program and pattern designing apparatus

A non-transitory computer readable medium having a pattern designing program stored thereon, the pattern designing method, when implemented by a processor, comprises:

• acquiring circuit design data, said circuit design data present, at least in part, in a technology file;
• carrying out transfer simulation calculation and a step simulation calculation by using physical layout data produced from the circuit design data;
• comparing a results of the transfer simulation calculation and the step simulation calculation with a preset standard;
• carrying out calculation of electrical characteristics by using parameters obtained from the physical layout upon determining that the preset standard is fulfilled as a result of the comparison, and carrying out calculation of the electrical characteristics in which the result of the transfer simulation calculation is reflected in the parameters upon determining that the preset standard is not fulfilled as a result of the comparison;
• and
• updating the technology file in accordance with the comparison when the preset standard is not fulfilled, said updating occurring prior to the calculation for electrical characteristics.
